FILTER AND CLEANER.

SPECIFICATION forming part of Letters Patent No. 622,698, d ated April 11, 1899. Application led October 28, 1895. Serial No. 567,143. (No model.)

To cir/ZZ whom t may concern:

Be it known that we, WILLIAM B. LINDSAY and WILLIAM E. TONNER, of Steubenville, in the county of Jefferson and State of Ohio, haveinvented an Improvement iu Filters and Cleaners, of which the following is a specification. y

This invention relates generally to iilters, and particularly to that class thereof known as porous-wall filters, in which the water is forced through the walls of a porous cylinder or receptacle.

More particularly stated, the invention is a device for cleaning the exterior of such receptacle, and is an improvement upon the devices shown, described, and claimed in our applications filed May 14, 1895, Serial No. 549,310, and .Iune l0, 1895, Serial No. 552,237.

The object of this invention is to avoid certain objectionswhich we have found in existing devices and to provide for a greater and steadier hydraulic pressure and also to distributed more evenly over the filteringsurface and at the same time the cleaning operation will be greatly facilitated.

With these objects in view our invention consists in the peculiar construction of the several parts and the novel manner of combining or arranging the said parts, all of which will be fully described hereinafter and pointed out in the claims. l

In the drawings forming a part of this specification, Figure l is a side view of our lter, partlybroken away. Fig. 2 is a vertical longitudinal section. Fig. 3 is a horizontal section on line 3 3 of Fig. 2. Figs. 4 and 5 show details of construction.

In carrying ont our invention we employ an outer case A, having a bottom ci, on which is produced a soclreted boss a. The filteringcylinder B is ofporous material and has a discharge-pipe C extending thereinto, said pipe being closed at the bottom by means of a nut c, which has a lug c adapted to iit in the socketed boss a', and thus act as a pivot for the filtering-cylinder when it is desi-red The porous filtering-cylinder is arranged eccentrically within the outer case and nearer the front side than the rear, the purpose of which is to allow ample space for the introduction of a cleaner or scraper D, which is preferably composed of natural stone of the character described in our Patent No. 528,104, dated October 23, 1894. This scraperD has a piston E centrally mounted upon the rear side, which piston projects through an opening c in the outer case and into the water-supply pipe F, which is preferably constructed with a globe-shaped chamber f, into which the rear end of the piston extends. This piston is made hollow and may be left open or partially closed at the rear end and near the forward end is provided with an upwardly-opening aperture G, through which the water issues in a ne stream and is sprayed against the top H of the outer case, and then streams down evenly upon the exterior of the filtering-cylinder.- The piston is made flat on one side, as shown at c', and the end of supply-pipe is similarly shaped, so that when said piston is set in a vertical position it cannot turn or become misplaced. The water passes through the supply-pipe and piston out through hole G,

land in doing so the cleaner of stone is pressed against the side of the filtering-cylinder. The cylinder being eccentric to the case and having the discharge-tube projected through the top, said top is made in two parts-namely, the cap-piece h, through which the pipe projects, and the clamping-ring h, which binds the cap-piece -to the top of outer case, a suitable packing-ring I being interposed to prevent leakage, and a stuffing-box Kvsurrounds the discharge-pipe, which is preferably constructed with a detachable curved end and a regulating-cock, whereby the discharge of ltered water can be regulated.

A discharge-faucet L is located at one side of outer case, near the bottom, and is used when cleaning the filter, as presently den scribed.

In operation the water is admitted through i the coupling and, passing through the supplypipe and tubular piston, is sprayed upward and upon the outer side of the scraper or cleaner and strikes against the dome-shaped cover of the outer case or receptacle, and in this manner is sprayed over the entire top of the filtering-cylinder. The water then streams down over the exterior surface of the iilter- IOO ing-cylinder, and thus renders the filtering operation quicker and easier.

Vhen it is desired to clean the exterior surface of the filtering-cylinder, the dischargefaucet is opened and the cylinder revolved by simply turning the discharge-pipe, and as the water is being sprayed over the entire exterior surface the cleaning operation can be accomplished very quickly and easily, and an abundance of hydraulic pressure will always be had through the medium of the tubular piston pressing against the tubular lug, producing, when the filter is full of Water, a thorough agitation and rapid circulation of the Water, cleaning perfectly Without emptying the ilter, as is necessary in others.

It will thus be seen that we provide a ilter in which the maximum pressure of the water is obtained at the desired point, and yet the water itself is uniformly distributed over the iltering-surface. It will also be noticed that by arranging the cylinder eccentrically ami ple room is provided for a stone cleaner, which stone cleans the cylinder evenly and thoroughly and much better than a metallic 0r composite cleaner.

While we have mentioned a natural-stone cleaner as best adapted for cleaning the filtering-cylinder, it is obvious that a metallic cleaner can be employed without departing from the spirit of our invention. The cleaner could also be projected against the cylinder by air-pressure, if so desired.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is- V l. In a filter of the class described, the com bination with the outer case and the inner filtering-cylinder, the cleaner and the supply-pipe, of the tubular piston attached to the cleaner, having a longitudinal bore, and upwardly-discharging aperture communicating with said bore, said piston having a flattened side, substantially as and for the pur'- pose set forth.

2. In a filter of the class described, the combination with the outer case, of an eccentric;

ally-arranged inner filtering-cylinder, and arranged between the inner and outer cases a scraper of natural stone, a tubular pistou attached to said scraper, said piston having a flattened lower side, and the water-supply pipe, and discharge-pipe, together with the discharge-faucet, all arranged substantially as shown and described.

3. In afilter, the combination with an outer cylindrical case, of an inner filtering-chamber, arranged eccentrically Within said case, the eccentric top and clamping-ring, and the discharge-tube extending from the inner cylinderthrough the eccentric top, and a scraper arranged between the outer case and the inner filtering-chamber, substantially as and for the purpose setforth.

4. In a filter, the combination with the outer cylinder, of a filtering-cylinder situated therein, an eccentric top to said filter, the ldischarge-pipe and draw-off cock, the inlet arranged about midway the height of the cylinders, a piston movable insaid inlet-pipe, a cleaner rigidly fixed to the inner end of said piston, said piston being tubular in form and closed at the inner end and having an opening in the upper side causing the stream to project upward toward the top ofthe cylinder, the inner cylinder being revoluble, and lthe cleaner being fixed, substantiallyas shown and described.

In testimony whereof We affix our signatures in the presence of two witnesses.
